England star Clifford ruled out
Jack Clifford will sit out England's opening Six Nations clash against Ireland through injury.
The 25-year-old has suffered a head injury while training with the rest of the England squad in Portugal and has returned home, meaning he will sit out the Dublin encounter.
England defence coach John Mitchell says it is nothing serious, but will be enough to keep him out of the game.
"Jack took a knock to the head so what we've decided to do is to manage him," said Mitchell. "It's not an HIA (head injury assessment) outcome but it's more important to manage him, so he's returned home early as he won't be able to get through most of the work remaining."
England are also waiting on key trio Owen Farrell, Brad Shields and Joe Cokanasiga and Mitchell says everything will become a lot clearer tomorrow.
"Our main session is on Wednesday. We'll be in a better position by then to know exactly where we'll be at with individuals," Mitchell added.
"Brad is progressing really nicely. He was in contact conditioning and is moving nicely.
"Owen has been integrating further and further as the sessions have gone on. He's very vocal and very energetic. It looks like he's enjoyed little bit of a break.
"He's been jumping into contact progressively and seems pretty good and isn't shirking any of his duties."
